1Principles

Neurovascular structures

There are no significant arteries, veins, or nerves on the lateral side of the knee.

There may be bleeding from the lateral genicular arteries, which will need to be controlled using diathermy.

At the posterior aspect of the knee lie the popliteal artery, nerve and vein. It must be borne in mind that these structures can be damaged by the injury, or can be damaged by the surgeon during the reconstruction.

Lag screw fixation of small metaphyseal fragments is to be avoided, as this will interfere with their blood supply and often does not add significant biomechanical stability to the final fracture fixation construct.
